I want to know what happens to an AWD Evo with 700hp when it loses it's stock spoiler. Does it some how make the car lose speed in drag racing, or does the car just lose it's performance in the turns?

I also want to know the same exact question, only for a FWD ralliart with 700hp when it loses it's stock spoiler.

I know the RA probably can't get that fast. This is just a hypothetical question. Thanks!

 

nothing really, spoiler on FWD cars dont help anything, it actually causes drag and makes it slower

 

That is not 100% true as this has been discussed before. Quick search will help you rewrite your answer.

 

the spoiler creates a higher drag coeficient, thus reducing top speed; on the other hand it increases rear downforce, so your back end stays planted a bit more, making cornering easier.

 

technically any car without a spoiler will create less drag, therefore being a bit quicker in a line. but obviously rear downforce can be an issue. an AWD car might be less noticeable because of the AWD, but i guess it still helps.

someday ull see civics with a front wing...or a non matching front bumper that has wings on it or sutting. sorry a lil

 

Thats what I thought. Losing the spoiler will make the car go faster as there will be less drag and rear downforce, but you will lose some stability at high speeds. Thanks guys.

 

It would be good if you try to find out the following points:

1. Drag.
2. Drag Point.
3. Turbulence.
4. Aerodynamics.

Once you understand its relationship, then it will help you understand the purpose of spoilers, wings, diffusers, carnards, splitters. 'Losing some stability at high speed' is a dangerous game bro......

 

sweeet...

 

You would be loosing more than " some stability" with a 700 hp car. If i was to be driving a 700 whp car it would most definetly have a spoiler. My integra had a spoiler that i could adjust the downforce, and in curiosity i adjusted it to 0. It turns out just like i thought that the benifits of having some rear spoiler down thrust outweigh not having any. The rear end of my car felt 10x lighter and on a back street thats not cool.

 

Good point. It is all abstract unless you have a basic understanding of aerodynamics.

There a are 4 aerodynamic forces.

1. Lift - overcomes weight for flight / is overcome by weight for land vehicles.
2. Weight - How much an object weighs. Opposite lift. Spoiler creates weight once the is enough airflow over it to become effective. aka downforce
3. Thrust- Forward force / Propulsion
4. Drag- A backward or retarding force that opposes thrust and limits speed.

So, a spoilerless car will have less drag (faster straight line) but will have less stability due to the lack of downforce (weight) that would have been produced by a spoiler.

 

Nice info for the drag racers!

 

Awsome info! Thanks!

So then I have nothing to worry about if I take the spoiler off of my ralliart which will only have around another 20hp than stock in the end. I don't think I need to worry about losing stability since my ralliart will only be about 185hp at the most after my intake, pully, CF and rims to lighten the load, and one other mod which I have not decided on yet. Probably a full exhaust.

Awsome. Thanks again everyone.

 

Ralli, It's not about horsepower here.

You could have a Yugo with 50hp but get it to speed and you still may have instability due to the aerodynamics working against the car.

Horsepower is irrelevant.

More speed = more airflow = the need for better aerodynamics

 

Yes. You will have nothing to worry about, but not for the reasons above. I doubt the RA spoiler offers any real downforce at all, as it is neutral in cut and more or less just for style.

That is a false statement. Wings/spoilers do create drag, yes, but the right wing or spoiler can add downforce making a car stick better and thus faster through corners that it would have to take slower without them - overcoming the drag effect. That goes for cars of any drivetrain layout.

 

food for thought - some wings are for reducing drag ie: integra type r wing, wheres the evo wing, and most gt type wings aid with downforce at the slight cost of drag.
